¨RTC ALARM (optional, active only with ATX type power supply)
PC system can be waked up by the RTC setting in the CMOS. You can set the
alarming date and time in the RTC memory, When RTC alarms, the PC system will
be triggered and wakes up automatically.
Enable the “Resume by Alarm” selection in the BIOS setup utility, and then input
the accurate date and time in following fields. (the “RTC Alarm Resume” is
included in the “POWER MANAGEMENT SETUP”, please refer to Section 4.7),
Having stored the RTC alarm setting, the PC system will be turned on automatically
according to the date and time which is recorded in the CMOS memory.
Same as the above, you have to reboot the PC system and wait for the POST (Power
On Self Test) is completed to enable the RTC alarm.
¨MODEM RING-IN (optional, active only with ATX type power supply)
This mainboard can be triggered by a modem ring-in signal. When you have an
external modem installed, you can use it to power on the PC system. When there is
the incoming message from the external modem, the PC system will be triggered by
the ring-in signal and wake up automatically to receive the message for you.
In order to use the ring-in signal to wake up your PC system, you will have to use
the EXTERNAL MODEM and have it connected to one of the Serial Ports (COM1
or COM2). When the system power is off, this mainboard will continue to detect the
serial port status. When it detects the ring-in signal from the serial port, the system
power will be turned on and start to receive the incoming messages automatically.
To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the “Modem or LAN resume” option (it is in the “POWER MANAGEMENT
SETUP”, please refer to Section 4.7 for the settings). Having completed the BIOS
setup, you have to reboot the PC system so that BIOS can verify the setting. (the
“DMI pool data” will be verified by the BIOS when loading the operating system).
Simply speaking, shut down the PC system and then re-start the system. The modem
ring-in feature will be enabled when the operation system has been loaded.
